Locked? It hasn't veered off topic or got nasty enough - yet! Here goes …
I have my smallish radiant hand fed somewhat centered in a ~700ft^2 room with 9’ ceilings that is insulated with 18” of fiberglass batting. Maybe you can get the picture of my layout but the net is the house is set up to move heat from the stove. The stove room is on the east side. In winter, the room stays ~72* except when sitting with 10’ of the stove. Ceiling temps are in the 80s. To the immediate west through a 6’ x 7.5’ opening is a dining room that opens to a two story foyer and an opening (no header, ceiling dumps to the foyer and dinette) into the dinette/kitchen/ family room filling out the rest of the north west side of the house. Tucked in by its self some 50 straight line distance from the stove is a parlor room (no doors) in the south west corner that opens to a hall off the foyer and to the family room. It is always the coldest room (low 60s, high 50s) that we rarely use. Surrounding the second floor of the foyer is a walk way. The four bedroom doors face this open foyer. Open a bedroom door and it warms from the ~68* heat trapped at the top of the foyer. They are never very cold. The heat I feel in the dinette, several corners and two rooms away, feels great compared to the same temperature produced by the oil fired warm air furnace. This comfort difference is because of the radiant heat source.
IMHO, this thread peppered with creative wording defending one heating device over another has overlooked a few common physical facts. Heat moves, more than one way or another. Usually for us it’s a combination of radiant and convective movements. We can influence how it moves and how it gets there. Sometimes, the basic laws of the physic that supports this movement are overlooked. Radiant heat is more directional in relation to the space it comes from and the surface area of the radiant source (how much stove/baseboard/radiator surface area). Radiant waves don’t go around corners. They warm objects in direct line of the stove. Like sound waves, they bounce around via the objects in their path, their intensity diminishing based on the capacity of the source, distance and number turns involved in traveling to distant points. Once the stove heats an object in direct line with the stove, the heated object then has enough energy to re-radiate that energy. Both radiant and convective energy is moved to the distant rooms by the constant bath of radiant heat from my little radiant stove constantly chugging out the BTUs.
A central system places numerous satellite BTU sources throughout the house and evens out the spread of heating energy. A single (or multiple) stove(s) has to be sized and placed in a space that will allow the heat to move to where it’s needed (duh!) I’ll never give up the Vigilant II (no electric needed) and plan to install a central warm air system to piggy-back on the warm air oil furnace duct system. One or the other and likely both will do the trick but coal will be primary. If I ever replace the Vigilant, it will be with a larger baseburner.
Well, that was my long-winded shot at summing this thread up, hopefully without any hidden barbs. Okay, fire away! I can take it
